A robot called Cheetah¹ has set a new world speed record for legged robots, running faster than the fastest human.

一个名叫猎豹的机器人创造了有腿机器人的速度记录，其速度比最快的人类还要快。

The headless machine, funded by the Pentagon, reached 45.5km/h when tested on a treadmill².

Jamaican sprinter³ Usain Bolt's top speed is 44.7km/h.

The project is part of efforts to develop robots for military use. One robotics expert told the BBC that it was "unfortunate" the Cheetah was made primarily "to kill people".

It has been created by the Massachusetts robotics company Boston Dynamics⁴ and backed by the US Defense⁵ Advanced Research Projects Agency (Darpa).

According to Darpa, the aim is to "more effectively assist war fighters across a greater range of missions".

The Cheetah, which is powered by a hydraulic⁶（液压的） pump, broke its own record of 29km/h, recorded in February.

"The Cheetah had a slight advantage over Bolt as it ran on a treadmill," Darpa said in a statement, "but most of the power Cheetah used was to swing and lift its legs fast enough, not to propel itself forward."

The agency plans to test the robot in the field in 2013.

Killing⁷ civilians⁸?

The machine's design has been inspired by the real cheetah, the fastest land animal, which can reach speeds of 121km/h.

"Cheetahs¹⁰ happen to be beautiful examples of how natural engineering has created speed and agility¹¹ across rough terrain," said Gill Pratt, Darpa programme manager.

"Our Cheetah bot borrows ideas from nature's design to inform stride patterns, flexing¹² and unflexing of parts like the back, placement of limbs and stability."

"What we gain through Cheetah and related research efforts are technological¹³ building blocks that create possibilities for a whole range of robots suited to future Department of Defense missions."

Noel Sharkey, professor of artificial intelligence and robotics at the University of Sheffield, said the robot was "an incredible technical achievement, but it's unfortunate that it's going to be used to kill people".

"It's going to be used for chasing people across the desert, I would imagine. I can't think of many civilian⁹ applications - maybe for hunting, or farming, for rounding up sheep.

"But of course if it's used for combat, it would be killing civilians as well as it's not going to be able to discriminate¹⁴ between civilians and soldiers."
